Which two vasopressors are specified to mix into IV fluids for hypotension management?

• A. Ephedrine and Phenylephrine
• B. Epinephrine and Norepinephrine
• C. Dopamine and Dobutamine
• D. Vasopressin and Terlipressin

Answer: (A)

During sedation, when blood pressure drops, a combined IV vasopressor approach can be used to quickly restore tone and maintain cardiac output. Ephedrine provides both alpha and beta effects, increasing heart rate and contractility along with some vasoconstriction, which helps raise the pressure and improve overall output. Phenylephrine, on the other hand, is a strong alpha-1 agonist that primarily increases vascular tone and systemic vascular resistance, producing a rapid rise in blood pressure with less direct stimulation of the heart. Using them together allows for a balanced correction: the vasoconstrictive effect of phenylephrine elevates pressure while the beta effects of ephedrine support heart rate and cardiac output, giving smoother hemodynamic control than using either alone. Mixing these into IV fluids can standardize dosing and provide prompt, adjustable support during hypotensive episodes. Other vasopressors exist, but this combination specifically pairs a potent vasoconstrictor with an agent that boosts cardiac output, which is the common pairing described in this context.
